[PMID: 39179996 PMCID: PMC11342647 DOI: 10.1186/s12886-024-03629-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Accepted: 08/12/2024] [Indexed: 08/26/2024] Open
Abstract
OBJECTIVE This study aimed to determine the proportion of poor visual outcome and associated factors among adult patients who underwent cataract surgery at Debre Markos and Felege Hiwot Comprehensive Specialized Hospitals in northwestern Ethiopia in 2023. METHODS A hospital based cross-sectional study was conducted on 418 adult patients who had undergone cataract surgery from June 07 to August 07, 2023. Patients were recruited using systematic random sampling with an interval of 2. A pre-tested semi-structured questionnaire, medical record review, and ophthalmologic examination were used to collect data. The collected data was entered into Epi-info version 7 and exported to SPSS version 25 software for analysis. Binary logistic regression was used to determine the factors associated with poor visual outcomes of cataract surgery. Variables with a p-value of less than 0.05 in the multivariable binary logistic regression were considered statistically significant. RESULTS A total of 408 study participants with a median age of 65 years and a response rate of 97.6% took part. The proportion of poor visual outcomes of cataract surgery from 4 weeks to one year was 25.7% (95%CI: 21.6%, 30.3%). Factors responsible for poor visual outcomes of cataract surgery were intraocular lens implantation without a posterior chamber (AOR = 2.91, 95%CI:1.46,5.80), per-existing central corneal opacity (AOR = 3.83, 95%CI:1.52,9.69), pseudoexfoliation (AOR = 3.91,95%CI:1.39,11.88), age-related macular degeneration(AOR = 3.75, 95%CI:1.22, 11.88), glaucoma (AOR = 3.11, 95%CI:1.06,9.17) and striate keratopathy(AOR = 3.4, 95%CI: 1.11, 10.88). CONCLUSION In this study, the proportion of poor visual outcomes of cataract surgery is higher than the World Health Organization recommendation. The study found that implantation of an intraocular lens without a posterior chamber, pre-existing central corneal opacity, pre-existing age-related macular degeneration, pre-existing glaucoma, pseudoexfoliation, and striate keratopathy were significantly associated with poor visual outcomes of cataract surgery. We recommend that ophthalmologists and cataract surgeons prioritize the reduction of surgical complications and pre-existing ocular co-morbidities to enhance post-operative visual acuity. Improving pre-operative assessment and refining surgical techniques like phacoemulsification will aid in achieving this goal.

Abstract
Background Cataract is the leading cause of blindness and the second leading cause of visual impairment worldwide, accounting for 51% and 33% of all cases, respectively, in low- and medium-income countries bearing a disproportionately high burden. Hence, this study aimed to assess the visual outcome of age-related cataract surgery and identify factors associated with patients' postoperative visual outcomes in Jimma University Medical Center, Southwest Ethiopia. Methods An institution-based cross-sectional study design was conducted among 386 cataract surgery patients from January 1, 2016, to December 30, 2017. The study participants were selected using a systematic random sampling technique. Data were collected by reviewing the selected patients' medical records using a pre-tested checklist, entered into EpiData version 3.1, and exported to SPSS 20 for analysis. Proportions, summary statistics, and tables were used for presentations of the findings. Binary logistic regression was carried out to identify independent predictors of visual outcome. Findings were presented with adjusted odds ratios and their 95% confidence interval. A p-value <0.05 was used to declare a statistically significant association. Results About 231 individuals (59.8%) had poor visual results following cataract surgery. Furthermore, age >70 (AOR = 3.64; 95% CI [1.35-9.82]), preoperative ocular co-morbidities (AOR = 2.34; [1.32-4.15]), incision-based cataract surgery (AOR = 7.11; [3.16-16.02]), compared phacoemulsification operated by resident surgeons (AOR = 2.19; [1.23-3.89]), presence of intraoperative complication (AOR = 3.41; [1.47-7.92]), lens remnant (AOR = 2.91; [1.11-4.92]), ocular inflammation (OR = 2.56; [1.34-4.92]), and striate keratopathy/corneal edema (AOR = 1.91; [1.07-3.44]) were significantly associated with poor visual outcome. Conclusion The visual outcome following cataract surgery fall below WHO recommendation. In this study, age, ocular co-morbidities, surgical method, surgeon status, intraoperative complication, SK, and ocular inflammation associated with post-operative Uveitis and anterior chamber reaction were associated with a poor visual outcome.

Abstract
Background Visual outcomes and factors associated with cataract surgery vary from country to country and within countries. This study aimed to evaluate associated factors and visual outcomes following cataract surgery among adults attending Saint Paul’s Hospital Millennium Medical College (SPHMMC), Addis Ababa, Ethiopia. Patients and Methods We conducted a prospective, longitudinal study of consecutive adult patients scheduled for cataract surgery between May 2018 and April 2019. Preoperative, intraoperative and postoperative data were collected and analyzed using SPSS version 23.0. Descriptive statistics and binary logistic regressions were used to analyze the data. We used World Health Organization (WHO) criteria for cataract surgery outcome assessment as a reference for comparison. Results Three hundred fourteen eyes of 314 participants (mean age 64.16±8.83 SD, 52% females, 44% from rural location) were included in the study. Most, 283 (90.1%) had preoperative visual acuity less than 6/60. At final follow-up visit (6 to 8 weeks), best-corrected visual acuity (BCVA) was good (≥6/18) in 215 (68.5%), borderline (<6/18–6/60) in 63 (20.1%) and poor (<6/60) in 36 (11.5%) eyes. Age-related macular degeneration (AMD) [OR = 4.57, 95% CI [1.12–17.24], p=0.03] and preoperative astigmatism [OR = 3.22, 95% CI [1.25–8.33], p=0.01] were significantly associated with poor postoperative visual outcome. Conclusion While the majority of patients had good postoperative BCVA following cataract surgery, the percentage of patients with poor visual outcomes was higher than the WHO standard. Greater attention to pre-existing co-morbidities such as retinal disease and high astigmatism could improve outcomes by optimizing patient selection and surgical approach.

Abstract
AIM To examine the coexistence of diabetes mellitus (DM) and cataract in Hungary. The effects of DM on the cataract surgical results were also in the focus of analysis. METHODS Statistical data analysis of the results of the Rapid Assessment of Avoidable Blindness with Diabetic Retinopathy (RAAB+DR) module conducted in Hungary in 2015. This cross-sectional, population-based, national survey included 3523 people aged 50 years and over. Participants of the survey were examined on-site. Visual acuity, main cause for visual impairment (using direct and indirect ophthalmoscopes), in case of best corrected visual acuity (BCVA) ≤0.5 and blood glucose level (random test with glucometer) were examined. RESULTS The prevalence of cataract was 23.4%, and DM was 20.0%. The occurrence of cataract steadily increased with age. Among the examined participants with DM, the prevalence of cataract was significantly (P=0.012) higher (+35%) than that in non-diabetic subjects (29.5% vs 21.8%). Following aging (OR=15.2%, P<0.001), DM proved to be the most independent influencing risk factor (OR=49.9%, P<0.001). The presence of DM was neither an influencing factor for complications of cataract surgery, nor for postoperative visual acuity. CONCLUSION DM appears to be one of the main risk factors for developing cataract. Other risk factors, such as age, sex and environment also play an influencing role. Diabetes does not seem to affect the occurrence of cataract surgical complications.

Abstract
BACKGROUND In 2019 the German Commission for the Prevention of Blindness (DKVB) held an eye camp in the Tanzanian town of Sumbawanga. For patients with mature cataracts and the ability to see light cateracts were treated by manual small incision cataract surgery (MSICS). For the first time in this camp the quality of the results of the cataract operations was measured. OBJECTIVE The quality of the cataract operations is presented and the results were assessed in the context of the guidelines of the World Health Organization (WHO). METHODS Those patients who had a cataract operation in the first week were examined during the second week with respect to the parameters vision, refraction, split lamp microscopic findings, results and complications after surgery. The results were retrospectively evaluated and compared with the guidelines of the WHO. RESULTS A total of 42 postoperative patients from the eye camp could be examined within 5-9 days after cataract sugery. The following parameters were found: median postoperative visual acuity 0.26, spherical equivalent -2.82 dpt, astigmatism -2.2 dpt, axis 113°. Visual acuity >0.3 in 14.2% (WHO 80%), vision 0.1-0.3 in 62% (WHO 15%), vision <0.1 in 23.8% (WHO 5%). Prolonged healing time and intraocular irritation in 29% of the cases. CONCLUSION Although the vision improved, the results are sobering when taken in the context of the WHO guidelines. The postoperative refraction showed a myopic shift and an high level of astigmatism. The reasons are manifold: ocular comorbidities, limited diagnostic and therapeutic possibilities in a nonclinical setting. Other factors are the kind of training of the staff in the camp, the difficult circumstances and advanced findings. Consideration of the results of this study is imperative to be able to measure the quality of the work and to create the potential to make future improvements.

Abstract
AIM Immunologic dysfunction was recently found to be one of the most important mechanisms underlying the initiation and development of atherosclerosis. Thymus involution can contribute to immune disturbance and disequilibrium of T-cell subsets. This study aimed to explore whether recent thymic emigration (RTE) is impaired in patients with coronary artery disease (CAD). METHODS Content of signal-joint T cell receptor excision circles (sj-TREC) in T lymphocytes, a molecular marker of RTE, was assessed among CAD patients and age-matched controls. Monochrome multiplex quantitative PCR method was used to assess the samples' telomere length in order to exclude the potential influence of T cell proliferation on the dilution of sj-TREC. Patients were grouped according to Gensini score (GS) (low, GS <18; intermediate, GS 18-41; high, GS >41). Ordinary logistic regression models were used to determine potential risk factors for CAD and GS tertiles. RESULTS Average copy numbers of sj-TREC per 10(6) T lymphocytes among patients with unstable angina, stable angina, and controls were 726±429, 1213±465, and 1795±838, respectively (P<0.001). However, there was no significant difference in telomere length among groups. Moreover, the content of sj-TREC in the high GS group was most significantly reduced than the low GS group (P<0.001). Multivariate logistic regression analysis revealed that lower sj-TREC was independently associated with the progression of CAD (OR=0.44, P<0.001) and higher GS (OR=0.4, P<0.001). CONCLUSION Impaired RTE could be partly responsible for CAD development. Mechanisms may be involved in the disturbance of T lymphocyte compartment and interruption of maintained immune tolerance resulting from thymus involution.
